Electronic device and circuit board

Abstract

According to one embodiment, an electronic device includes a housing, a circuit board housed in the housing, and a reinforcing member. The circuit board has a first surface and a second surface on the rear of the first surface. The first surface has a first electronic component mounted thereon. The second surface has a second electronic component mounted thereon at an opposite position of the first electronic component. The reinforcing member includes a base member and a bridge. The base member is provided on the second surface to reinforce a first mount area on which the first electronic component is mounted. The bridge passes through the first mount area, and extends, across and over the second electronic component, from at least two points on the base member.

1 . An electronic device comprising:
 a housing;   a circuit board in the housing comprising:
 a first surface, on which a first electronic component is mounted, and 
 a second surface formed on a reverse side of the first surface, on which a second electronic component is mounted opposite to the first electronic component; and 
   a reinforcing frame comprising:
 a base portion on the second surface configured to reinforce a first mounting area on which the first electronic component is mounted, and 
 a bridge configured to pass through the first mounting area, and extend from at least two points on the base portion across and over the second electronic component. 
   
     
     
         2 . The electronic device of  claim 1 , wherein the bridge is supported by the housing at substantially center of the bridge. 
     
     
         3 . The electronic device of  claim 1 , wherein the base portion surrounds the first mounting area in a substantially rectangular manner. 
     
     
         4 . The electronic device of  claim 3 , wherein the bridge is configured to extend between diagonally opposite corners of the base portion in a substantially rectangular shape surrounding the first mounting area. 
     
     
         5 . The electronic device of  claim 3 , wherein the bridge is configured to extend between opposite sides of the base portion in a substantially rectangular shape surrounding the first mounting area. 
     
     
         6 . The electronic device of  claim 1 , wherein the bridge is cross-shaped. 
     
     
         7 . The electronic device of  claim 1 , wherein the bridge is I-shaped. 
     
     
         8 . A circuit board comprising a first surface and a second surface formed on a reverse side of the first surface, the circuit board comprising:
 a first electronic component mounted on the first surface;   a second electronic component mounted on the second surface opposite to the first electronic component; and   a reinforcing frame that comprises
 a base portion on the second surface configured to reinforce a first mounting area on which the first electronic component is mounted, and 
 a bridge configured to pass through the first mounting area, and to extend from at least two points on the base portion across and over the second electronic component. 
   
     
     
         9 . The circuit board of  claim 8  in a housing, wherein the bridge is supported by the housing at substantially center of the bridge.
